Rapidly deployable emergency communication system

Claim 2

In a deployable emergency communication system, apparatus comprising: a. a portable communications center, having receiving and transmitting means, adapted to be transported to the scene of an emergency for temporary use thereat, b. a plurality of portable/mobile transceivers of limited range, and c. a plurality of portable, self-contained repeaters adapted to be deployed within an area at said scene to provide repeater services between (i) two or more portable/mobile transceivers, (ii) between portable/ mobile transceivers and said communications center, and/or (iii) between portable/mobile transceivers, one or more other repeaters in sequence, and said communications center as required by the deployment pursuant to a particular emergency, at least one of said repeaters comprising: (1) receiving means, (2) transmitting means, and (3) control means for (a) directing said repeater receiving means to periodically scan a plurality of carrier frequencies, (b) selecting one of said scanned frequencies upon reception of said frequency containing an appropriate access signal, (c) selecting a transmitter frequency from a plurality of possible transmitter frequencies, and (d) directing said repeater transmitting means to retransmit on said selected transmitter frequency intelligence contained in said received frequency minus said access signal but including an access signal for the next adjacent receiving means to which said transmission is directed.

Claim 3

The apparatus of claim 1 wherein at least one of said portable/mobile transceivers includes means for generating and transmitting at least one access code signal for an adjacent receiving means.

Claim 4

The apparatus of claim 2 wherein at least one of said transceivers transmits a plurality of distinct access code signals and said control means in at least two of said repeaters select frequencies upon receipt of different ones of said distinct access code signals.

Claim 5

The apparatus of claim 3 wherein said plurality of distinct access code signals are digital data words.

Claim 6

The apparatus of claim 1 wherein said repeater control means include a microcomputer.

Claim 7

The apparatus of claim 5 wherein said microcomputer includes means for programming its functions.

Claim 8

The apparatus of claim 6 wherein said means for programming are responsive to signals received by said repeater receiving means.

Claim 9

The apparatus of claim 6 wherein said communications center includes means for transmitting programming signals for said means for programming.

Claim 10

The apparatus of claim 8 wherein at least one said transceivers transmits a plurality of distinct access code signals and said control means in at least two of said repeaters select frequencies upon receipt of different ones of said distinct access code signals.

Claim 11

The apparatus of claim 1 wherein said repeater control means includes means for preempting normal reception functions in response to reception of a priority access signal.

Claim 12

The apparatus of claim 10 wherein at least one of said plurality of portable/mobile transceivers has means for transmitting a priority access signal.

Claim 13

In a deployable emergency communication system, the method comprising: a. providing (i) a portable communications center having receiving means and transmitting means, (ii) a plurality of self-contained repeaters having receiving means, transmitting means, and programmable control means, and (iii) a plurality of portable/mobile transceivers, b. transporting said communication center to the scene of an emergency for temporary use thereat, c. deploying said repeaters within an area at said scene in accordance with a plan for providing repeater coverage within said area, d. programming said control means in each of said repeaters to: (1) direct its receiving means to periodically scan a plurality of carrier frequencies capable of being transmitted by (i) said communications center, (ii) one or more of said portable/mobile transceivers, and/or (iii) other repeaters depending upon the function of the particular repeater in said area, (2) select one of said scanned frequencies upon receipt of said frequency containing an appropriate access signal, (3) select a transmitter frequency from a plurality of possible transmitter frequencies capable of being received by (i) said communications center, (ii) said portable/mobile transceiver, and/or (iii) other repeaters depending upon the function of the particular repeater in said area and said access code contained in said selected receiver frequency, and (4) direct its transmitting means to retransmit on said selected transmitter frequency intelligence contained in said received frequency minus said access signal but including an access signal for the next adjacent receiving means to which said transmission is directed.

Claim 14

In a deployable emergency communication system, the method comprising: a. providing (i) a portable communications center having receiving means and transmitting means, (ii) a plurality of self-contained repeaters having receiving means, transmitting means, and programmable control means, and (iii) a plurality of portable/mobile transceivers, b. transporting said communication center to the scene of an emergency for temporary use thereat, c. deploying said repeaters within an area at said scene in accordance with a plan for providing repeater coverage within said area, d. programming said control means in each of said repeaters to: (1) direct its receiving means to periodically scan a plurality of carrier frequencies capable of being transmitted by (i) said communications center, (ii) one or more of said portable/mobile transceivers, and/or (iii) other repeaters depending upon the function of the particular repeater in said area, (2) select one of said scanned frequencies upon receipt of said frequency containing an appropriate access signal, (3) select a transmitter frequency from a plurality of possible transmitter frequencies capable of being received by (i) said communications center, (ii) said portable/mobile transceiver, and/or (iii) other repeaters depending upon the function of the particular repeater in said area and said access code contained in said selected receiver frequency, and (4) direct its transmitting means to retransmit on said selected transmitter frequency intelligence contained in said received frequency minus said access signal but including an access signal for the next adjacent receiving means to which said transmission is directed.

Claim 15

The method of claim 12 wherein said step of programming said control means is performed in part before said deployment of said repeaters and in part after said deployment of said repeaters.

Claim 16

The method of claim 13 wherein at least part of said part of said programming step performed after deployment is performed by transmitting signals to at least one repeater from said communications center.

Claim 17

The method of claim 13 further comprising the step of reprogramming said control means by transmitting signals from said communications center in accordance with a revision to said plan for providing repeater coverage.
